Summary: Purchased specifically to fit my HP LCD flats creen monitor, and it fit. Was so easy to install (less than a minute and most of that time was spent unpacking it). I use this for online meetings and the occasional Utube video, not for music.

Summary: Terrible product; although not the fault of anyone other than the designer. Its incredibly difficult to install on the monitor, and then is in the way of the cables so its very hard to hook them back up. The USB power supply isn't isolated at all, and thus you can hear all your machine's IO through the speakers even at fairly low volume levels. If it wasn't so hard to remove from the monitor I'd be returning it. But hey, glad I didn't pay list price.
Summary: The speaker connected to my HP ZR24w monitor without problems. The two included thumbscrews were not needed; in fact, there's no provision for them on this monitor. The speaker sounds pretty good considering it's size (it's bass response is weak.) It sounds just as good as, or better than, most inexpensive computer speaker systems. I configured the HP speaker bar as a center speaker, so a wide acoustic range isn't critical.
